Peri-prosthetic joint infection (PJI) is a serious complication of prosthetic joint arthroplasty. A better understanding and reversal of modifiable risk factors may lead to a reduction in the incidence of incisional (superficial and deep) and organ/space (e.g., PJI) surgical site infections (SSI). Recently, the Centers for Disease Control and Prevention (CDC) and the Healthcare Infection Control Practices Advisory Committee (HICPAC) published the Guideline for Prevention of Surgical Site Infection. This targeted update applies evidence-based methodology in drafting recommendations for potential strategies to reduce the risk of SSI both across surgical procedures and specifically in prosthetic joint arthroplasty...

Candida species are commensals but some develop biofilms in prosthetic materials and host surfaces that may represent up to 30% of deaths related to infections, particularly in immunosuppressed patients. Tumor necrosis factor (TNF) exhibits a plethora of functions in host defense mechanisms whereas excessive release of TNF in inflammation promotes tissue damage. Cytokines released in an inflammatory milieu may influence the development of microorganisms either by promoting their growth or displaying antimicrobial activity...

Repair of an incisional hernia (IH) generates costs on several levels and domains of society. The aim of this study was to make a complete cost analysis of incisional hernia repair (IHR) with synthetic and biological mesh and to compare it with financial reimbursement. Patients were grouped into three levels to determine the complexity of their care, and hence, the costs involved. Group 1 included patients without comorbidities, who underwent a "standard" incisional hernia repair (SIHR), with synthetic mesh...

Incisional hernia remains a very common postoperative complication. These are encountered with an incidence of up to 20 % following laparotomy. These hernias enlarge over time, making the repair difficult, and serious complications like bowel obstruction, strangulation and enterocutaneous fistula can occur. Hence, elective repair is indicated to avoid these complications. Implantation of a prosthetic mesh is nowadays considered as the standard treatment due to low hernia recurrence. The most common mesh repair techniques used are the onlay repair, sublay repair and laparoscopic intraperitoneal onlay mesh (IPOM)...

INTRODUCTION: Cross-linking and anti-calcification of prosthetic heart valves have been continuously improved to prevent degeneration and calcification. However, non-calcific structural deteriorations such as cuspal dehiscences along the stent still require further analysis. MATERIAL AND METHOD: Based upon the previous analysis of an explanted valve after 7 years, a fresh commercial aortic valve was embedded in poly(methyl methacrylate) (PMMA) and cut into slices to ensure the detailed observation of the assembly and material structures...

Odontogenic myxoma (OM) is a non-metastasizing neoplasm of mesenchymal origin, arising in the tooth-bearing areas of the jaws. When regarding the whole spectrum of differential diagnoses for osteolytic jaw lesions, OM constitutes a benign tumor rarely located in the maxilla. Radiographically, displacement of teeth and frequent involvement of the sinus will be found with advanced maxillary OM. The tumor can be removed by means of several techniques, ranging from conservative measures to extended surgical procedures that differ according to type of bone resection and reconstruction of the defect...

BACKGROUND: Theoretically, dynamic thoracic compliance (DTC) should be reduced by vertical expandable prosthetic titanium ribs (VEPTR) since titanium rods, scar tissue and ossifications increase stiffness of the rib cage. The effect of VEPTR on thoracic compliance has not yet been elucidated. The impact of VEPTR on the development of sagittal balance has not been fully investigated. PATIENTS AND METHODS: In a retrospective study, we investigated 21 consecutive children who were treated by VEPTR from 2004 to 2011 and three control groups...

Advanced forearm prosthetic devices employ classifiers to recognize different electromyography (EMG) signal patterns, in order to identify the user's intended motion gesture. The classification accuracy is one of the main determinants of real-time controllability of a prosthetic limb and hence the necessity to achieve as high an accuracy as possible. In this paper, we study the effects of the temporal and spatial information provided to the classifier on its offline performance and analyze their inter-dependencies...

Enucleation and evisceration are the most common surgical procedures that are performed to manage tumor, trauma, and infection. Given the consequences of surgical intervention, the conditions of the remaining eye socket may affect future prosthetic rehabilitation. A custom-made ocular prosthesis can be used to help restore the esthetics and functional defects and to improve the quality of life of patients with such conditions. An assessment must be performed on the prosthetic outcome before rehabilitation. The etiology of defect, type of surgery, condition of the remaining socket, and patient's age should all be considered...

AIMS: The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM...
